HORSE-POWER HEB-ENGINE.

SPECIFICATION forming part of Letters Patent No. 356,778, dated February1, 1887.

Application filed October 26, 1885. Serial No. 180,970.

To aZZ whom it may concern.-

Be it; known that l, Mil'r'rnnwhlonron, of Romeo, county of Moconib,State of Michigen, have invented n new and useful Improvement inHorse'Power Firc'Engines; and I declare the following to he a full,clear, and exnot description of the some, such as will ennble othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drnwin gs, which form a port of thisspecification.

My invention relates to certain new and useful improvements inhorse-power fire-engines, as more fully hereinafter described, and morefully pointed outin the claims.

The object of my invention is more espe cinlly to produce a combinedfire-engine and trendnnill horse-power which shall be simple in itsconstruction, not liable to get out of order, efficient in itsoperation, which may be easily transported, and readily put into use.

Still more definitely, while it is the purpose of my invent ion tocombine such an engine as I hereinafter describe with any suitablehorsepower, itis my design to combine said engine with on improved horsepower for which United States Letters Patent; were granted to me of dateApril 27,1880, No. 227,037, as such a horsepower as l have therein shownand described possesses runny decided advantages for such a combination;yet I would have in distinctly understood that. I do not limit myself toa horsepower of that; particular construct-ion; but I regard thecombinasion of such an engine as 1 herein describe with any suitablehorse-power as coming within the scope of my present invention,whichIcnrry out as follows:

In the drawings, Figure 1 is a side elevation of a device embodying myinvention. Fig. 2 is a, plan view; and Fig. 3 is a separate horizontalsectional view through the slrein of one of the wheels, with a port-ionof the frame supportin g one end of the crank-shaft.

A of the drawings represents any suitable horscpower. The particularhorsepower shown is that described in my patent above referred to,consisting of efrnme, A, provided with an endless chain, 153.

A represents skeins bracketed upon the frame.

. A represents the supporting-wheels located thereon.

(X0 model.)

a is the journal-box, located in the enlargeincuror recess in the innerend of the skein.

A? is the shaft passing through said journalboxes and skeins, said shaftbeing provided atone end with n crank-arm, a, and at the other end withn balance-wheel, a". The shaft; A is indicated in Fig. 2 in dottedlines, as also its pinions a a driven by the endless chain.

A and A are the shafts near each end of bhe horse-power, provided withpinions c a", meshing with the curved ruck-bars A and A secured to sillsA and rods of and aficonnecbing each set of rack-bars upon oppositesides of the fro-me, said rods provided with cranks A, for operating thepinions. a represents pawls to lock said pinions engaged with saidrack-bars. I

The wheels upon which the frame is suspended are located midway of theends of the frame, permitting either end of the frame to be raised andlowered by mennsof the rack-bars.

*When it is desired to transport the device, the sills A are run up onthe proper end, when the weight of the entire frame comes upon thewheels, and there being but; the two supporting-Wheels the device may beturned in a narrow compass. When desired for use, either ends of thesills A are lowered, as desired, by means of the adjacentrnck-bcrs andtheir pinions, so that the power rest-sfirm and steady. As stated insaid patent, the chain may be elevated at any desired angle, and theoperation of the power is reversible.

I will now proceed to describe the fire-engine combined therewith.

B is a. bracket or frame secured. upon the frame A of the horse-power,said bracket engnged about one of the supporting-wheels of their-nine Aand serving to support the pumps and their attachments.

O and 0 represent any suitable pumps. 0 and 0 represent pistons foroperating the same.

In the accompanying drawings I have shown two pumps; but I would have inunderstood that I contemplate one or more pumps as coming within thescope of my invention.

I do not limit myself to any particular construction of the pumpsthemselves, as any variety or construction of pumps may be employedwithout; departing from the principle of my invention. Preferably theyare double acting, and provided with air-chambers o.

. a sliding yoke, D, constructed with an elongated slot, as shown inFig. 1, in which the crank-pin of the shaft A is engaged, said pinpreferably adjustable in the crank-arn1 a, to give more or less throw,and provided with a roller to ridein said slot of the yoke D. Said yokeis supported by the pistons and by rollers d d, bracketed beneath theyoke, additional guide-rollersd and (Z ,being also bracketed above theyoke. By this construction it is evident that by the rotation of theshaft A the pistons will be alternately reciprocated in thepump-cylinders.

Commonly in treadmill horse-powers the drivingsha'lt is located at oneend of the device, instead of midway of the frame, and itis evident thatmy invention is adapted for use with such a power as well as with theparticular power herein described.

By combining the engine with a tread-power it is evident that thecombined machine may be transported and used in narrow placesas, forinstance, alley-wayswhere a sweep o horse-power cannot be used, andtherefore be machine, if desiredas,for instance,a reel may be wheeled upupon the chain for transportation and be readily removed therefrom foruse.

What I claim is 1. The combination, in a horse-power fireengine, of acranked drivingshaft, pumps connected by inlet and outletpipes, asliding yoke connecting the pump-pistons with the crankarm of thedriving'shaft, and guide-rollers located above and below said yoke,substantially as described.

2. A portable horse power fire-engine comprising an adjustable frame, areversible horsepower, one or more pumps supported by the power-frame, acranked driving-shaft, and a sliding yoke for connecting the crank-armof said shaft to the pump-pistons, substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
